I was referring to the question

>  to indicate that an argument to a method is optional

not to the typing of single arguments.

I also prefer lists with meaningful variable names with sigils.

This makes it easier for users to simply copy and adapt it.

Though probably

fetch_clients( $names_aref )

Is better written as

fetch_clients( \@names )
